Drain Tempering Valve (DTV)
Drain water from commercial equipment exceeding 140°F (60°C) can be costly – leading to failed inspections, fines, business interruptions, or injury and damage to personnel and equipment.
ThermOmegaTech’s Drain Tempering Valve (DTV) tempers excessively hot drain water to comply with international plumbing code temperature regulations. Thermostatic and completely self-operating, the DTV is plug-and-play, giving you one less thing to worry about.

How It Works:
The DTV tempering valve is installed into the drain line such that the hot effluent passes over the thermal actuator of the DTV, which controls the cold water inlet port. If the hot effluent is above the specified set-point of the valve, the DTV opens to allow cold water injection. As the hot effluent cools, the DTV automatically modulates to reduce the cold-water inlet flow. At 10°F below the full open temperature, the cold-water inlet is fully closed to conserve water.
Since the DTV is open only when the effluent exceeds the specified set-point temperature, it conserves water by automatically turning off cold water when not needed. Available in ½”, ¾”, and 1” sizes in brass or stainless steel, the DTV provides a convenient, economical, and easy-to-use method of tempering hot effluent flows.
You will need to calculate the flow rate to help you choose the correct size valve for your application. Check out the DTV FLOW CALCULATOR for assistance.
Valve Components:
| ITEM | DESCRIPTION | MATERIAL |
| 1 | Valve Body | Brass or 300 series stainless steel |
| 2 | Thermal Actuator | 300 series stainless steel |
| 3 | Operating Spring | 300 series stainless steel |
| 4 | Ram-Type Plug | 300 series stainless steel |
| 5 | Seat Seal | PTFE |
| 6 | Piston | 300 series stainless steel |
Typical Applications:
The DTV is used in applications where a high-temperature discharge flow from commercial equipment must be tempered with cold water before entering a public drain or sewer system. Applications include humidifier discharge to sewer or drain, commercial dishwashers or ware washers, boiler blowdown drain lines, and autoclave discharge.
Recommended Accessories:
For DTV installations, most local plumbing codes will require the installation of a check valve or backflow preventer to isolate the drain line from the potable water. A water hammer arrestor must be installed between the DTV and the check valve/backflow preventer if a check valve or backflow preventer is used. Failure to do so may cause permanent damage to the DTV and void the warranty. ThermOmegaTech offers an optional water hammer arrestor and backflow preventers to make life easier. Contact us or your local representative for more information on these products.
